With the number of warm weather teams we are getting I'm starting to believe, a little, that a winter schedule might be possible in a few years?
Let's say with expansion our Southern teams are:
1. Atlanta, 2. Houston, 3. Miami, 4. Orlando, 5. Los Angeles 6. Los Angeles 7. San Antonio 8. Carolina 9. Tennessee 10. Dallas, 11. San Jose 12. Sacramento 13. San Diego 14. Arizona 15. DC United
That would be 50% of the league in areas were it averages 45 degrees or higher in December, January, and February.
You could go heavy on Northern home games in August, September, and October (~2 Northern games for every 1 Southern game). Start switching to a more Southern schedule in November and December (~2 Southern games to 1 Northern game or whatever). Take a 4 week break for January. Start up with Southern games only for 2 weeks that would get you into mid-February, which is just a couple weeks earlier than MLS starts now, and you can maintain the ~2 to 1 ratio of Southern games until March and regular service could resume for March, I assume playoffs would start mid-April and end in lay May?
Then the playoffs would be in the warm months. I think I like that.
